Voting Under Way in Crimea Referendum to Join Russia

As voting continues in Crimea on a referendum to break away from Ukraine and become a part of Russia, the United States and Russia have agreed to push for Ukrainian constitutional reforms as a solution to its political crisis.

During a phone call Sunday, U.S. Secretary of State John Kerry told Russian Foreign Minister Sergei Lavrov the United States will not recognize the referendum. But Kerry and Lavrov agreed to seek a solution to the crisis in Ukraine by supporting constitutional reforms that include power sharing and decentralization.

Reuters news service reports Ukrainian Prime Minister Arseny Yatsenyuk is vowing to track down those promoting separatism in Crimea. He said Ukraine will find all ringleaders of separatism who are trying to destroy Ukrainian independence.

Meanwhile, Ukraine's acting defense minister told reporters the defense ministries of Ukraine and Russia have agreed on a truce in Crimea until March 21.
